AMID the current rock revival fueled by the Strokes, White Stripes and the Hives, few would imagine the surprising success of a choral symphonic pop band with 24 members clothed in white robes.

Yet Polyphonic Spree, a gospel-edged ensemble from Dallas, has become the latest rage – performing five sold-out shows in New York this week.

Led by ex-Tripping Daisy frontman Tim DeLaughter, the mega-group caught fire in March at the South By Southwest music festival in Autin, Texas, where even the most jaded rock critics were delighted by DeLaughter’s uplifting songs.

“It was all about sound, but there’s a spirit that comes along with it,” DeLaughter told The Post, fresh off the plane from London where Spree had played the Royal Festival Hall for David Bowie’s Meltdown Festival. “With 24 people, it’s overwhelming. You end up with a musical movement.”

Ten members form the choir, while the rest play a variety of instruments – horns, violins, guitars, drums, keyboards and even a theremin.

Take the Beach Boys’ orchestral pop, add a dash of Flaming Lips quiver and fold in some “Godspell” exuberance – and you’ll get a mild idea of the sound.

But its the live performance – with all these folks happily crammed on a small stage – that puts it over the top.

“This was my wish-list band,” says DeLaughter, 36. “I’m a fan of sunny pop music. It says so much about who I am.”

After Tripping Daisy guitarist Wes Berggren died of a drug overdose in 1999, DeLaughter decided to form the new group – and his other bandmates signed on.

“We rehearsed in my living room, then played a show,” he says. “It went crazy from there.”

And the cult-like white robes? “I thought it would be distracting if people were in their street clothes. These unify the band.”

The group recorded the album “The Beginning Stages of . . . The Polyphonic Spree” as a demo, and handed it out to fans at a Christmas show. Now it’s being released by Good Records.

“Everyone around me told me, ‘It would never work. You’ll never make money,’ ” says DeLaughter. “But I knew there was nothing like this.”

Remaining shows are tonight at Mercury Lounge, tomorrow at Northsix (Brooklyn), Saturday at Knitting Factory and Sunday at Village Underground.
